SETUP: Position a Reebok step or similar platform lengthwise to a wall. Stand on top of the step with the body perpendicular to the wall. Position the feet so one is close to the edge (support leg), and the other dangles over the side (free leg). Use the wall for balance if needed.

STEPS: Start with hands on the hips and balancing on the support leg. Keeping the free leg straight, perform a single leg squat on the support leg until the heel of the free leg lightly touches the ground. Do not transfer weight to the touch leg, but immediately return to the start position. Keep the hips level throughout the entire exercise. Keep the eyes looking forward and the chest up. Slow, controlled movements are best.

REPETITIONS: Perform three to five sets of 10-15 repetitions on each leg.
